During the reaction of photochemically generated silylenes Me2Si: with benzyl bromide, 1H-CIDNP (chemically induced dynamic nuclear polarization) is observed in the radical abstraction-recombination product PhCH2-SiMe2Br formed from singlet states of Me2Si:.

The photochemical decomposition of 7-sila- and 7-germa-norbornadienes (1a,b) was studied by the CIDNP 1H technique.The reactions proceeds by a two-step mechanism via the reversible formation of singlet biradicals, II.The triplet biradical (II), formed as a result of S-T conversion of (II)(S), irreversibly decomposes giving Me2E (E = Si, Ge).The insertion of Me2E into the C-Br bond of PhCH2Br and the Sn-Cl bond of Me3SnCl occurs via a radical mechanism, as deduced from the CIDNP effects observed in these reactions.
